This paper addresses drayage routing problems with heterogeneous fleets, compatibility
constraints, and truck load configurations. In these problems, containers can be of any size …

This paper develops an efficiency-based interactive dynamic technique to design the post-
disaster rescue route by combining the data envelopment analysis (DEA), traveling …

In this article, we study a load-dependent vehicle routing problem (LDVRP) to devise a
delivery plan for vehicles carrying various types of products (with different quality and …

A crucial practical issue encountered in logistics management is the circulation of final
products from depots to end-user customers. When routing and scheduling systems are …
